Appendix A.
The Dell™ PowerEdge™ R910 contains both volatile and non-volatile (NV) components. Volatile
components lose their data immediately upon removal of power from the component. Non-volatile
components continue to retain their data even after the power has been removed from the
component. Components chosen as user-definable configuration options (those not soldered to the
motherboard) are not included in the Statement of Volatility. Configuration option information
(pertinent to options such as microprocessors, system memory, remote access controllers, and
storage controllers) is available by component separately. The following NV components are present
in the PowerEdge R910 server.
Server BIOS Memory (SPI Flash, IC)
Size:
Type [Flash PROM, EEPROM]:
Can user programs or operating system write
data to it during normal operation?
Does it retain data when powered off?
Purpose? [boot code]
How is data input to this memory?
How is this memory write protected?
Server CMOS (Complementary Metal-Oxide Semiconductor) Memory
Size:
Type [Flash PROM, EEPROM]:
Can user programs or operating system write
data to it during normal operation?
Does it retain data when powered off?
Purpose? [boot code]
How is data input to this memory?
How is this memory write protected?
Remarks
Server BMC (Baseboard Management Controller)/iDRAC Express Boot Block Flash

which is executed by booting up the system
from a floppy or OS-based executable containing
the firmware file and the loader. System loaded
